Get that aggressive and sharp BMW sound without any check engine lights or in cabin drone. The Supersport X-Pipe Valvetronic exhaust system includes Fabspeed's high-performance Valvetronic axle back section and our "Double-X" mid-pipe that deletes the secondary catalytic converters, for the perfect combination of sound, power, and weight reduction.
SOUND:
This system transforms the M3/M4 into a proper sounding monster. You’ll actually hear some turbo spool when letting off the throttle and you’ll feel the gritty iconic BMW straight six sound coming through the cabin under hard acceleration. Adding more pops and bangs on downshifts and giving a throaty rumble at idle.
